Stéphane Penso Put on your scientist's gown to test ShockOut anti-vibrators: an article that should interest those who tend to suffer from elbow pain.

Today, the main challenge for a player of padel will keep his elbow and shoulder safe from injury.

The palas of padel, in addition to being heavier than tennis, squash or badminton rackets, are also those rackets that emit the most vibrations (excluding Basque pelota). The ShockOut company has been studying the issue for many years, and has thus been able to refine and enhance a whole range of innovative products.

The Higher Technical School of Industrial Engineers of the Polytechnic University of Madrid has carried out a study on the functionality of ShockOut shock absorbers. She came to the conclusion that the company's patented shock absorbers have “real utility as an anti-vibration element”.

And what was the study? (Be careful, it's very technical!)

Well thanks to a complete analysis of dynamic tests on the oscillatory response of the frames, with and without shock absorbers, FRF (Frequency Response Function) results were obtained.

From this observation, an analysis of frequency modularity was studied by integrating the weighting and the analysis in octaves defined in the UNE-EN-ISO 5349 standard.Measured mechanical vibrations and evaluation of human exposure to hand-transmitted vibrations' ”(April 2002).

At the time of the study, both hard and soft gum palas were used. After the dynamic tests on the different models, it was observed that all the palas vibrated, which is normal given that the frames are “deformable solids”. In turn, the dynamic behavior was recorded and a comparative analysis of the vibration level was assessed when incorporating the anti-vibration devices. To this end, the frequency response functions (FRF) obtained in the tests were interpreted and they confirm the major utility of these “dampeners”.

The various comparisons have shown that when the shock absorbers are incorporated into the holes, the level of vibratory acceleration in the handle is reduced and, consequently, the harmful effects of said vibrations. The comparison is therefore obvious; the level of vibration emitted by the blades with and without ShockOut antivibrators, and the results obtained, have shown that, in all cases, the modular acceleration (RMS) is significantly lower when shocks are included.

What are the advantages of these antivibrators?

Intrigued by the benefits of this new system, we wanted to learn more and, from ShockOut, we revealed some of its main features:

  • Vibration reduction: with this unique system, the company ensures a reduction of oscillations up to 92%!
  • Optimization : the shock absorbers make it possible to vary the balance of the pala. With use on the top of the racket, they can influence its performance and thus gain power, or have more control if they are positioned towards the shaft. They can also frame the sweet-spot to make it increase, or be placed in the corners, so that the hitting surface acquires greater tension.
  • Comfort: a great hitting improvement is seen when the dampers are mounted on the blade, especially when placed on the upper part (power / violence). In this case, we will not only notice that the vibrations disappear but also that the sensations improve.
  • Solidity : the inserted shock absorbers are unbreakable. Sustainable purchase that can be transposed at each change of pala.
  • Synergy : they allow the blade to gain body, making it more solid. The dampers with their cylindrical shape, housed on both sides, make the blade structurally improved, being more robust, so that cracks and breaks take longer to appear.
  • Customization : they are marketed in different colors. Therefore you can choose the best combination that will best suit the cosmetics of your frame.

Make way for practice

Now that all these technical elements are available, what about use?

The set-up is childishly simple. 99% of the palas having a profile of 38mm, there will be no compatibility problem, both in terms of depth and of the diameter of the drilling, because the ShockOut is made of a malleable material that perfectly matches shapes.

All you have to do is insert 4 “gadgets” in the holes, turn the racket over, and proceed in the same way (at the location) on the other side. To take them out, a pick will be necessary (guitarists will appreciate, included in the pack), in order to allow disengagement without risk of degradation.

I first placed the ShockOut on the upper part of the Babolat Technical Viper, a power focused diamond shaped pala!

The result is absolutely clear!

No more vibrations observed (on the punto dulce) and greatly improved playing comfort. In addition, I increased my punching power with the addition of these welcome few grams!

I then inserted the antivibrators at the bottom of the Counter Viper, and indeed the control was greatly improved, while clearly muting the bad oscillations. If you don't want to change the scale of your pala, you can still opt for a “smart” 50/50 split, but this is not recommended by the factory.

It is an essential product for those who want to protect their joints and take care of their ligaments.

With this innovation, you will play more relaxed without apprehending the pains while playing and especially those after match. In addition, you can change the behavior of your pala by influencing the strategic arrangement of the dampeners according to the desired playing style.
